THREAD-EYE FOR LOOMP'SHUTT'LES.

To all whom it may concern:

Be it known that I, FREEMAN OAss, a citizen of the United States, and residing at Brooklyn, Kings county, State of New York, have invented certain new and useful Improvements in Thread-Eyes for Loom- Shuttles, of which the following is a specification.

This invention relates to improvements in thread guides for weaving shuttles of the general type shown in Patent No. 1,188,005 to John R. Mitchell. The present invention comprises means for securely holding a porcelain or other vitreous guide in a metal casing, the latter being adapted to be so: cured in the eye of a shuttle. tion also comprises means for positioning the vitreous guide in the casing so that the lateral opening in the guide will always accurately register with the corresponding opening in the casing.

Referring to the drawings Figure 1 is a side view of a guide;

Fig. 2 is a similar view partly broken away looking in the direction of the arrow, Fig. 1;

Fig. 3 is a section on the line 3-3 of Fig. 2;

Fig.1 4- is a section on the line 1-4: of Fig. 3; an

Fig. 5 is a perspective view of the three parts of the device, separated.

Referring to the drawings, 10 indicates a cylindrical metal casing having a lateral opening 11 extending about half way about its circumference and a longitudinal slit 12 connecting said opening with one end of the casing. The opening 11 may be termed the eye of the casing. To the casing is fitted a metal cap 13, which as shown has two lugs 14 adapted to fit in notches 15 in the end of the casing in order that the cap when applied may always occupy the same relative position on the casing. The cap is provided with an internal rib 16 for a purpose to be presently explained and with an external rib 17 to properly locate the casing and cap in a shuttle. vThe cap is also provided with a central inwardly projecting stud or anchor 18.

The thread guide proper is a body of vitreous material preferably porcelain 20 adapted to fit in the cylindrical casinglO and having a shoulder 19 which abuts against a shoulder 21 of the interior of the casing to locate the guide 20 longitudinally The inven- Specification of Letters Patent.

therein. which projects into the cap 13 is provided wlth a groove 22 into which fits the rib 16 to properly locate the porcelain guide axially in the casing. The guide is also providedwith an axial opening 23 to receive the stud 1S, and in which the stud or anchor is securely and permanently retained by suitable cement.

The procelain guide is provided with a lateral eye 24 which registers with the eye 11 in thecasing l0 and with the longitudinal slit 25 which registers with the slot 12 in the casing. Theeye2 l and slit 25 open into each other and into a longitudinal central cylindrical opening 26 in the porcelain body which preferably terminates in a flaring mouth 27 In assembling the parts the porcelain body 20 is passed into the casing 10 until the shoulder 19 abuts against the shoulder 21. The cap is then cemented permanently to the porcelainbody with the rib 16 in the groove 22 and the lugs 14 in the notches 15. This mode of assembling will bring the eyes 11 and 24 and the grooves 12 and 25 into register and the device will be in condition to insert in the eye of a shuttle. The rib l7, cooperating with a suitable groove in the eye of a shuttle will properly locate the device in the shuttle.

The porcelain body below the shoulder 19 is preferably slightly smaller than the interior of the metal shell 10 so that it will not be affected by contraction and expansion of the metal and the space between the shell and body is preferably filled with a layer, 30, of felt, fabric, or other cushioning material to prevent breakage of the porcelain or vitreous body, due to shock or jar in the operation of the shuttle. It is to be noted that the several parts will always be assembled in the same relation and maintained in proper relation when in use.

Having thus described the invention what is claimed as new and desired to be secured by Letters Patent is:

1. A thread guide for loom shuttles comprising a hollow cylindrical metal casing having lateral and longitudinal thread openings, a cylindrical vitreous thread guide having corresponding thread openings, 3. metal cap for the casing, means for securing the cap to the vitreous guide, and means onsaid guide for holding the metal casing in contact with the cap.

The end of the porcelain guide 2. A thread guide for loom shuttles commeans to revent relative rotation a c lin-- drical vitreous thread guide fitting within the casing and cap, means for preventing relative rotation between the guide and cap, and means for securing said parts together.

3. A thread guide for loom shuttles comprising a hollow cylindrical casing having a notch in its end, a cap fitting the end of the casing and having a lug to engage the notch and an inwardly projecting rib, a vitreous thread guide fitting within the easing and having a groove cooperating with said rib, and means for securing said parts together.

4. The combination with a hollow cylindrical casing open at its ends and having lateral and longitudinal thread receiving openings, of a cap fitted to one end of the casing with means for preventing relative rotation, a. vitreous thread guide fitting within the 'casing and cap with means for preventing relative longitudinal and rotary movement therein, and means for securing said parts together.

5. A thread guide for loom shuttles comprising a hollow cylindrical metal casing having lateral and longitudinal thread openings, a vitreous thread guide within the easing having corresponding thread openings, and a metal cap, the cap being permanently anchored to the thread guide and adapted to hold the casing in proper position on the guide.

6. A thread guide for loom shuttles comprising a hollow cylindrical metal casing having thread openings, a cylindrical thread guide of vitreous material, having corresponding thread openings, said guide being arranged concentrically within the casing, and a lining of soft material between the casing and guide to protect the latter.

In testimony whereof I afiix my signature.
